Articles produits par le groupe ondes gravitationnelles
Détecter des ondes gravitationnelles demande de gérer une grande quantité de données. Il faut trouver un signal rare caché dans le bruit du détecteur. Comment les équipes de Virgo réalisent-elles…

Abstract: We search for gravitational-wave signals associated with gamma-ray bursts detected by the Fermi and Swift satellites during the second half of the third observing run of Advanced LIGO and…
Les détecteurs Virgo et LIGO ont observé 35 nouveaux événements d'ondes gravitationnelles, entre novembre 2019 et mars 2020, pendant la deuxième partie de la troisième période d'observation de LIGO et…
We present the prospects for the pre-merger detection and localization of binary neutron star mergers with third-generation gravitational-wave (GW) observatories. We consider a wide variety of GW networks that may…
Abstract: (APS) We search for gravitational-wave signals produced by cosmic strings in the Advanced LIGO and Virgo full O3 dataset. Search results are presented for gravitational waves produced by cosmic…
Gravitational-wave observations became commonplace in Advanced LIGO-Virgo’s recently concluded third observing run. 56 nonretracted candidates were identified and publicly announced in near real time. Gravitational waves from binary neutron star…

Abstract: (Oxford University Press) GRANDMA (Global Rapid Advanced Network Devoted to the Multi-messenger Addicts) is a network of 25 telescopes of different sizes, including both photometric and spectroscopic facilities. The…
Abstract: (IOP) We present the prospects for the early (pre-merger) detection and localization of compact-binary coalescences using gravitational waves over the next 10 yr. Early warning can enable the direct…
